first time poster here so here it goes.

i have a 2004.5 Rail line 600 cummins, 2500 quad cab with 8' bed. just recently my front end has started squeaking really nasty when i take big bumps, so i got under and have determined that it is my spring on the right front tire, i first coated it in litium grease, not effect, then in oil, and finally in WD-40. still sqeaking and starting to get worse. i am a college student and cant afford to take it to the dealer. anybody have any ideas?

 

Check all your bushings up front. A lot of times this is all it is. They get worn and crack, and in turn squeak!

 

it sounds like the body mount right behind the front tire. mine does that or did until i pulled the bolt and coated the damn thing with lithium grease. the mounts dry up and its dry rubber against metal.....lovely noise eh?
